KEYS TO HIGH QUALITY LINT AND SEED WITH A COTTON MODULE BUILDER Robert B. Metzer, James R. Supak and Roy E. Childers * Use of the cotton module builder as a storage and transport system has increased since the early 1970s. In 1982 more than 2,700 module builders were used to module over 60 percent of the Texas cotton crop. Several factors are responsible for the rapid accept- ance of these machines. These include allowing the harvest operation to be independent of trailer availa- bility and ginning capacity and permitting cotton harvest to proceed uninterrupted during favorable weather conditions. The module builder has helped stabilize cotton acreage in areas with declining numbers of gins. This is attributed to the improved handling and transport system associated with the module builder which permits a more orderly ginning operation. Module storage allows gins to process cotton at a more constant rate even when intermittent rainy periods temporarily stop field harvest operations. Although there are definite benefits associated with the use of the module builder, associated problems develop in moduling unprocessed cotton containing lint, seed and nonlint material as harvested by stripper or spindle picker harvester. A large portion of this problem is attributed to improper harvesting techniques which frequently result in damp seed cotton going into module storage. Further quality loss is associated with improper building and covering of modules. Reduced lint and seed quality during stor- age costs the industry millions of dollars each year. Excessive moisture in seed cotton not only re- duces quality after a period in storage, but it also increases the weight of seed cotton which contributes to lower gin turnout and higher ginning cost. Wet modules can reduce ginning capacity up t0 50 per- cent. The cost involved in ginning hot, wet modules becomes prohibitive with current high energy and labor costs. *Respectively, Extension cotton specialist, Extens
